On 20 July 2018 around 21:50 local time, ESA astronaut Alexander Gerst welcomed the legendary electronic band Kraftwerk and 7500 visitors to the Jazz Open Festival on Stuttgart's Schlossplatz – live from the International Space Station, where he will live and work until mid-December 2018. During the call with space, Kraftwerk founding member Ralf Hütter and Alexander played a special duet version of the track Spacelab, for which Alexander had a tablet computer configured with virtual synthesizers on board. With thanks to Kraftwerk for sharing this video footage.
